History Of Partogram• Friedman's partogram•

A prolonged latent phaseB prolonged active phase

C arrest active phase

Abnormal progress in labor

Philpott alert and action line

Alert line ( health facility line )

• The alert line drawn from 3 cm dilatation represents the rate of dilatation of 1 cm / hour

• Moving to the right or the alert line means referral to hospital for extra care

Action line ( hospital line )• The action line is drawn 4 hour to the right of

the alert line and parallel to it• This is the critical line at which specific

management decisions must be made at the hospital

Normal labor progress

• At addmision • Then after 4h

Abnormal labor progress

Obstructed labour
